Jurors in the US federal death penalty trial of the self-described white supremacist accused of killing nine black churchgoers in Charleston were hearing his recorded confession to the carnage Friday. Prosecutors intend to play the two-hour taped confession, marking the first time the public will hear Dylann Roof speak about his alleged grisly June 2015 crime at length. Roof's own mother had a heart attack during a survivor's tearful testimony and had to be hospitalized on Wednesday.
